It<br>is compatible with a 0.014" guidewire, and at a minimum, a<br>5F guide catheter (≥ 0.058").<br><br>OptiCross is intended for use with the BSC iLab™ imaging<br>console (K072517) and Boston Scientific's next generation<br>motor drive unit, MDU5 PLUS™ . When used together, the<br>catheter, motor drive unit (MDU), and iLab equipment form a<br>complete imaging system that allows for ultrasonic<br>examination of coronary intravascular pathology.<br><br>The catheter consists of two main components: the catheter<br>body and the imaging core. | {1}------------------------------------------------ Device Description, continued The catheter body consists of four sections: the telescope assembly, proximal shaft, distal shaft, and the distal guidewire lumen. The proximal shaft, distal shaft, and distal quidewire lumen comprise the usable length of the catheter (135 cm). The proximal telescoping section remains outside of the guide catheter. The distal guidewire lumen (1.6 cm) is used to track the catheter along the guidewire and incorporates a radiopaque marker band (0.5 cm from the distal tip). The distal shaft serves as a flexible and acoustically transparent imaging window. The proximal shaft provides pushability to the distal imaging window and serves as a lumen to the imaging core. Two insertion markers are located on the proximal shaft (90 and 100 cm from the distal tip). These markers facilitate estimation of catheter position relative to the distal tip of the quide catheter. The telescope assembly allows the imaging core to be advanced and retracted up to 15 cm. The corresponding movement of the transducer occurs from the proximal end of the quidewire lumen to the proximal end of the imaging window. The telescoping shaft includes 16 incremental markers for lesion length assessment (1 cm apart); the 5-cm. 10-cm, and 15-cm markers are distinct. The outer surface of the catheter body also employs a hydrophilic coating to enhance lubricity and promote deliverability (distal 23 cm). The imaging core consists of a proximal hub assembly and a rotating drive cable that houses a piezoelectric (PZT) transducer at the distal imaging window. The hub assembly (1) provides an electro-mechanical interface between the catheter and the motor drive unit and (2) incorporates a oneway check valve that is used to flush the interior of the catheter body. The catheter must be flushed with heparinized saline prior to use, as this provides the acoustic coupling media required for ultrasonic imaging. The drive cable and PZT transducer rotate independently of the sheath assembly to provide 360° image resolution. The transducer converts electrical impulses sent by the motor drive in to transmittable acoustic energy. Reflected ultrasound signals are converted back to electrical impulses, returned to the motor drive unit, and are ultimately processed by the iLab equipment for visualization. # Inended Use/Indications for Use This catheter is intended for ultrasound examination of coronary intravascular pathology only. Intravascular ultrasound imaging is indicated in patients who are candidates for transluminal coronary interventional procedures. {2}------------------------------------------------ Device Technoogy Characteristics and Comparison to Predicate Device The OptiCross™ Coronary Imaging Catheter maintains the same fundamental scientific technology and operating principles as the predicate device, iCross. In addition, the shelf-life, packaging configuration, sterilization methodology, and indications for use remain unchanged. The OptiCross Coronary Imaging Catheter incorporates new design features intended to enhance deliverability, reliability, and overall ease of use when compared to iCross™ (K111043). Modifications with respect to the predicate device include: a new hub interface with the motor drive unit, an optimized proximal to distal shaft transition, reductions to proximal sheath profile and the distance between the transducer and distal tip, a narrower distal housing profile and transducer aperture, as well a narrower imaging window and guidewire exit port (crossing profile). In addition, 16 incremental markers (1 cm apart) have been added to the male telescope tube to aid in lesion length assessment. Material changes have been made to the hub seal, male telescope tube, proximal shaft, anchor housing, distal tip, catheter strain reliefs, potting and distal housing adhesives, and also include utilization of lead-free solders and flux. In support of a substantial equivalence determination, Boston Scientific has compared and evaluated the material and design differences between the subject and predicate device. Non-clinical performance evaluations, as described below, indicate that the subject device is substantially equivalent to. and at least as safe and effective as the predicate device (iCross). {3}------------------------------------------------ ## Non-Clinical Performance Data Determination of substantial equivalence is based on an assessment of non-clinical performance data. Non-clinical data includes bench-top performance evaluations, packaging validation, biological safety, and acoustic output testing. ## Bench Testing: Bench testing was performed to evaluate physical integrity. functionality, and performance of the catheter. Performance criteria includes deliverability, crossability, quide catheter compatibility, lubricity, retraction capability, image resolution, image penetration, non-uniform rotational distortion, image artifact, measurement accuracy, pullback reliability, general imaging capabilities, dimensional requirements, visibility under fluoroscopy, interface with ancillary devices, environmental requirements, user interface requirements, catheter robustness and simulated use structural integrity. ## Biological Safety Testing: The OptiCross™ Coronary Imaging Catheter was subjected to a series of biocompatibility tests in accordance with ISO 10993-1 (including genotoxicity), microbial assessments including bioburden and endotoxin, pyrogenicity, and sterility assurance. ## Acoustic Output Testing: Acoustic Output was evaluated in accordance with FDA Guidance, Information for Manufacturers Seeking Marketing Clearance of Diagnostic Ultrasound Systems and Transducers (September 9, 2008). Acoustic Output test results for the OptiCross ™ Coronary Imaging Catheter are below the FDA Track 1 limits. #### Packaging Validation: The integrity of the packaging configuration was tested in accordance with ISO 11607-1 and ISO 11607-2. Testing was conducted on fully packaged units after subjected to electron beam sterilization, climatic conditioning, and distribution challenge conditioning. #### Conclusion: Non-clinical performance evaluations, as described above, indicate that the subject device is substantially equivalent to, and at least as safe and effective as the predicate device, iCross™ (K111043). Clinical Performance Data Not applicable; determination of substantial equivalence is based on an assessment of non-clinical performance data. {4}------------------------------------------------ Conclusion New design features incorporated by the OptiCross™ Coronary Imaging Catheter do not affect scope of the intended use/indications for use, nor do they raise new concerns regarding safety or efficacy with respect to the predicate device. > As the indications for use and fundamental scientific technology have not changed, non-clinical performance data supports a determination that the subject device, OptiCross™, is substantially equivalent to the predicate device, iCross™(K111043); and that it is at least as safe and effective for its intended use. {5}------------------------------------------------ # DEPARTMENT OF HEALTH & HUMAN SERVICES Image /page/5/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
